4' Claims. (01. 19-6 1 This invention relates to new anduseful-"inlprovements in lambrequins for cotton gins.

In the ginning of cotton it is customary to 'allow the seed cotton to bepulled jup between them by the saws. seeds in the roll box have atendency to'fall back i through-the lambrequin and down between thehuller ribs, thus interfering with the operation With this arrangementthe of the gin.

' One object of the invention is to provide a lam brequin so arranged asto prevent the seedsfrom, falling back through the lambrequin into thebreast, thus assuring the retention of the seed in the roll box until ithas been delinted, and r then its discharge into the chute formedbetween the huller ribs and the gin ribs.

7 Still another object of the invention is to provide a lambrequin soarranged as to prevent the seeds in the roll box from fallingtherethrough and interfering with the upward pas- 7 between its longfingers for preventing sage of the seeds from the breast. I e I Afurther object of the invention is to provide a lambrequin having shortfingers arranged sage of seeds. a a A construction designed to carry outthe in 'vention will be hereinafter described together with otherfeatures of the invention. l i g The invention will be morereadilylunderstood from a reading of the following specification and byreference to the accompanying drawing in;

invention is shown, and

which an example of the wherein! e V V Figure 1 is a'partial verticaltransverse sectional view of a gin equipped witha lambrequin constructed in accordance with the invention,

Figure 2 is a partial plan viewof the lambrev quin showing portions ofthe adjacent saws, and Figure 3 is a vertical sectional view taken onthe line 33 of FigureZ.

In the drawing the numeral 10 designates a gin stand of the usual type.-A rib rail 11, commonly used ingin" stands, is provided for supv portingthe huller ribs-12 Gin saws'13 mounted on a saw shaft 14 and tweenthehuller ribs and act to carry thecotton and seeds up into the rollbox.

'Theseribs'are so shapedas to cause the cotton, that is not pulled immediately through them; toroll on top of the saws. We provide a lambrequin A which includes'a pipeor tubing '17 having-a'rod 20 fastened there in. Holes 18, equallyspaced, are drilled in this pipe and rodf and straight fingers l9 aredriven therethroughft. This is the usual construction. Intermediate thefingers 19 shorter fingers or pins 21 are mounted in the pipe and rod inthe same manner. Thus it can be seen that the saws can pull theseed'cotton up through the spaces B 'forin'ed between the fingers 19 andthe endsof the pins 21,. but the seed isprevented from falling l j 1After the cotton and seeds have passed between; the huller ribs 12 theyare brought into contact back through the lambrequin .bytheshort pins,

jThe lambrequin' now in general use has been found unsatisfactory mainlybecause the fingers 19 must be spaced far enough apart to allow theseedjto be pulled therebetween by the saws. Thus it can be seen thatthere is nothing to prevent the seeds from falling from'theroll vboxbackinl the breast and interfering with the gin,

operation. By providing the short pins 21 the seeds are held in the rollbox and yet sufficient s fingers adjacent the shaft or pipe 17 becauseof the tendency of theseeds to collect at the front of the roll box andpass down the inner facet of the rail 11 to the lambrequin.

Byusing the short pins between thefingers 00 l small seeds arepreventedfromlfalling between 1 the fingers adjacent the shaft; also theround pinspermit cottonlint to pass upward between the pins and thefingers.
